Problems solved by technology

[0006] Due to the low concentration of pollutants in polluted rivers, lakes, ponds and other water bodies, the water quality is generally better than that of the existing sewage treatment plants, so it is not suitable for purification by existing treatment measures
In these water bodies, some solid pollutants are likely to exist, and at the same time, the concentration of dissolved oxygen in the water body is low, and serious problems such as black and odorous water bodies occur.

Embodiment 1

[0038] Biological contact oxidation filter sedimentation tank. Its main structures include pool body 1, filtration system 2, water collection system 3 and aeration system 4. The filter system 2 is composed of filter cloth 9, mesh cylinder 8 and filler 10, and the biofilm is used as the main filter medium after the membrane is hung in the sewage. The water collection system 3 is a water collection pipe, and the filtration system 2 is vertically arranged. Through these structures, the pollutants in the sewage are removed by sedimentation, filtration and biochemical reactions.

[0039] The present invention is used for removing the pollutant in sewage, specifically comprises the following steps:

[0040] 1) Aeration

[0041] An aeration system 4 is set in the pool body 1 to aerate the sewage with oxygen, and the sewage undergoes aerobic biochemical reactions in the pool body;

[0042] 2) filter

[0043] The water level of the pool body 1 is higher than the water level of the...

Embodiment 2

[0050] Biological contact oxidation filter sedimentation tank. Its main structures include pool body 1, filtration system 2, water collection system 3 and aeration system 4. The filter system 2 is composed of filter cloth 9, mesh cylinder 8 and filler 10, and the biofilm is used as the main filter medium after the membrane is hung in the sewage. The water collection system 3 is a water collection side ditch, and the filtration system 2 is arranged horizontally. Through these structures, the pollutants in the sewage are removed by sedimentation, filtration and biochemical reactions.

[0051] The present invention is used for removing the pollutant in sewage, specifically comprises the following steps:

[0052] 1) Aeration

[0053] An aeration system 4 is set in the pool body 1 to aerate the sewage with oxygen, and the sewage undergoes aerobic biochemical reactions in the pool body;

[0054] 2) filter

[0055] The water level of the pool body 1 is higher than the water leve...

Embodiment 3

[0062] Biological contact oxidation filter sedimentation tank. Its main structures include pool body 1, filtration system 2, water collection system 3 and aeration system 4. The filter system 2 is composed of filter cloth 9, mesh cylinder 8 and filler 10, and the biofilm is used as the main filter medium after the membrane is hung in the sewage. Through these structures, pollutants in rivers, lakes and ponds are removed by sedimentation, filtration and biochemical reactions, and dissolved oxygen in water is increased.

[0063] The invention is used for removing pollutants in polluted rivers, lakes and pond water bodies, and increasing dissolved oxygen in water bodies. Specifically include the following steps:

[0064] 1) Aeration

[0065] An aeration system 4 is set in the pool body 1 to aerate and oxygenate the sewage. After rivers, lakes and ponds enter the pool body 1, pollutants in the water body undergo aerobic biochemical reactions in the pool body 1;

[0066] 2) fil...

Abstract

The invention relates to a bio-contact oxidation filter sedimentation tank which mainly comprises a tank body, a filter system, a water collection system, an aeration system and other facilities, wherein the common bio-contact oxidation tank, aeration tank, sedimentation tank and filter tank in sewage treatment are organically combined. The sewage is subjected to biochemical degradation and filter sedimentation in the facilities and then enters next process or is discharged after reaching the standard; and the settled sludge flows back or is removed. Through the invention, the treatment efficiency of the sewage treatment facilities can be improved, the energy consumption is lowered, and the investment and operation cost are reduced.

Description

technical field [0001] The invention belongs to the field of water pollution treatment and prevention, and in particular relates to a treatment method and facilities for sewage and sewage bodies. Background technique [0002] Water is the source of life. With the development of industry, agriculture and the tertiary industry, the shortage of water resources and water pollution have become the bottleneck of social development. The most important water pollution control measure at present is to build sewage treatment plants to remove pollutants in sewage. Sewage treatment plants mainly include urban centralized sewage treatment plants and scattered sewage treatment plants from various pollution sources. [0003] Biological contact oxidation tanks, aeration tanks, sedimentation tanks and filter tanks are common sewage treatment facilities in sewage treatment plants. In existing sewage treatment projects, these facilities mainly appear as independent structures. Due to the singl...
